Sumo Squats
Weights are optional, but if using, hold them right at the tops of your shoulders, elbows bent. Stand with feet slightly wider than shoulder-length apart.
Bending slightly forward at the hips and maintaining a flat back, bend your knees and squat low, until your thighs are parallel with the ground. Engage your glutes and squeeze as you go, pausing at the bottom for the full effect.
Stand back up straight, and repeat for 12 reps total.
